Email deliverability has become more challenging than ever. Google and Microsoft have tightened their spam filters, and new authentication requirements mean that poorly configured senders get blocked instantly.
The New Requirements
DMARC, SPF, and DKIM
All three authentication protocols are now mandatory for reliable inbox placement. If your domain isn't properly configured, your emails go straight to spam.
Volume Limits
Google now throttles senders who exceed 5,000 emails per day from a single domain. Smart senders use multiple sending domains and warm them up gradually.
Content Signals
Spam filters now use AI to evaluate email content quality. Generic, template-style emails get flagged more often than personalized, contextual messages.
